The Kyun Tou boxing form with the « wall punching bag » specific to Wing Tsun is the ideal training method for working on the Wing Tsun punch. More accurately, punch training with the wall bag and not the sand bag helps the student to get a feeling for the force and correct execution of his punch. Unlike the sand bag, the wall punching bag does not swing around or move backwards when struck. When the punch hits the wall punching bag, the aim is to direct the force into the bag, i.e. against the opponent. Working on punching with the wall punching bag focuses the concentration solely on the muscle groups and joints involved in the execution of the punch. Therefore, starting from different arm positions, various boxing combinations are exercised as single or double punching techniques, at varying heights and in different directions.
